.5 Mounting Notice As the case is made of resin, do not use excessive force while screwing in the mounting bracket. The torque is approximately 0.12N m. When the one-touch type mounting brackets are used: Mountable panel thickness is 1 to mm. Set the mounting bracket 1 to the top and bottom of the instrument first. Then, insert the GCS-00 2 from the front of the mounting panel. When the Soft-type Front-cover is used, mountable panel thickness is 1 to 2.5mm. 2 1 UP When the screw type mounting brackets (BL option) are used: Mountable panel thickness is 1 to 15mm. Insert the GCS-00 from the front of the panel. Attach the mounting bracket by the holes at the top and bottom of the case, and secure the unit in place with the screws. When the Soft-type Front-cover (FS-8-S) is used, mountable panel thickness is 1 to 1.5mm. (Fig..5-1) 1 Up Up (Fig..5-2).

Notice The terminal block of the GCS-00 is designed to be wired from the left side. The lead wire must be inserted from the left side of the terminal, and fastened with the terminal screw. Use a thermocouple and compensating lead wire in accordance with the input specifications of this controller. Use a -wire RTD according to the input specifications of this controller. This controller does not have a built-in power switch or fuse. Therefore, it is necessary to install them in the circuit near the external controller. (Recommended fuse: Time-lag fuse, rated voltage 250V, rated current 2A) For a 2V AC/DC power source, do not confuse polarity when using direct current (DC). With the relay contact output type, externally use an auxiliary electromagnetic switch in accordance with the capacity of the load to protect the built-in relay contact. When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources and load wires to avoid external interference. Solderless terminal Use a solderless terminal with an insulation sleeve in which an M screw fits as shown below.

. Running After the unit is mounted to the control panel and wiring is completed, operate the unit following the procedures below. (1) Turn the power supply to the GCS-00. For approx. 2 seconds after the power on, the sensor type characters and temperature unit are indicated on the PV display, and the input range high limit value is indicated on the display. See (Table.1-1). (If any other value is set during the high limit setting, display indicates the value.) During this time, all outputs and LED indicators are in status. After that, the PV display indicates the current temperature, and the display indicates the (desired value). While the Control output function is working, is indicated on the PV display. (2) Input each set value. Input each set value referring to Chapter 5 Operations. () Turn the load circuit power. Control action starts so as to maintain the control target at the.. Other functions (1) Input abnormality indication When the input value exceeds 999 (99.9), digits on the PV display flash. When the input value exceeds [Input range high limit value + 50 (100 )], the control output is turned (for DC current output type, OUT low limit value), and the PV display flashes. When the input falls below -199 (-19.9), digits on the PV display flash. When the thermocouple input value falls below -50 (-100 ), the control output is turned (for DC current output type, OUT low limit value), and the PV display flashes. For the RTD input, when Input range low limit value is -19.9, if the input value falls below -50 (-100 ), the control output is turned (for the current output type, OUT low limit value), and the PV display flashes. For the RTD input, when Input range low limit value is -199, if the input value falls below [-199 1% of the input span], the control output is turned (for DC current output type, OUT low limit value), and the PV display flashes. (2) Sensor burnout (Burnout) When the thermocouple or RTD is burnt out, the control output is turned (for DC current output type, OUT low limit value), and the PV display flashes. () Self-diagnosis The CPU is monitored by a watchdog timer, and when an abnormal status is found on the CPU, the controller is switched to warm-up status. () Automatic cold junction temperature compensation (thermocouple input type) This detects the temperature at the connection terminal between thermocouple and the instrument, and always keeps it at the same status as when the reference junction is located at 0 (2 ). 12

Troubleshooting If any malfunctions occur, refer to the following items after checking the power supply and wiring. 11.1 Indication Problem is indicated on the PV display. is flashing on the PV display. is flashing on the PV display. The indication of the PV display is abnormal or unstable. Presumed cause and solution Control output function is working. To release the function, press the key for approx. 1 second. Thermocouple or RTD is burnt out. [Thermocouple] If the input terminals of the instrument are shorted, and if a value around room temperature is indicated, the instrument is likely to be operating normally, however, the sensor may be burnt out. [RTD] If approximate 100 of resistance is connected to the input terminals between A-B of the instrument and between B-B are shorted, and if a value around 0 (2 ) is indicated, the instrument is likely to be operating normally, however, the sensor may be burnt out. Check whether the lead wire of thermocouple or RTD is securely connected to the instrument terminal. Check whether the polarity of thermocouple or compensating lead wire is correct. Check whether codes (A, B, B) of RTD agree with the instrument terminals. Check whether the sensor input is selected properly. Check whether the temperature unit ( or ) is correct. Check whether the sensor correction value is suitable. Check whether the specification of the thermocouple or RTD is correct. AC leaks into the thermocouple or RTD circuit. There may be equipment that interferes with or makes noise near the controller. 11.2 Key operation Problem Unable to set the, P, I, D, proportional cycle, alarm value, etc. The values do not change by the or key. The setting indication does not change within the input range even if the or key is pressed, and new values are unable to be set. Presumed cause and solution Set value lock (Lock 1 or Lock 2) has been selected. Release the lock mode. PID auto-tuning or auto-reset is performing. In the case of PID auto-tuning, cancel auto-tuning. In the case of Auto-reset, it takes approximate minutes until the auto-reset is finished. high limit or low limit may be set at the point where the value does not change. Set it to a suitable value while in Auxiliary function setting mode 1. 19
11. Control Problem The PV (process variable) does not rise. The control output remains in an status. The control output remains in an status. Presumed cause and solution Check whether thermocouple or RTD is burnt out. Check whether the lead wire of thermocouple or RTD is securely connected to the instrument terminals. Check whether the wiring of output terminals is correct. OUT low limit value is set to 100% or higher in Auxiliary function setting mode 2. Set it to a suitable value. OUT high limit value is set to 0% or less in Auxiliary function setting mode 2. Set it to a suitable value. For all other malfunctions, please contact our main office or dealers. Reg.
